Ridroid quests: why not?

So I've been wondering... On days where the Vegas field is the daily thing, why would you do the field over the Ridroid quest when hunting Vegas Illusia?

I know, I know, ridroid bad... But you're using them anyway in Vegas, the ridroids spawn more of the big stuff (or rare stuff), and Chroto has a quest for it.

I don't get it.

What goes down in Vegas, stays in Vegas.

Thankfully, the Ridroid went down in Vegas so it's easy to just not deal with, hahaha.

I suppose it's because it's not front and center as a recommended quest, just like the regular expedition.
